DTrace unable to dump typedef'ed argument
I found this on a FreeBSD 8.1 box... %dtrace -l -f rtalloc_fib -v ... Argument Types args[0]: struct route * args[1]: (unknown) The function defined in sys/net/route.c: void rtalloc_fib(struct route *ro, u_int fibnum) u_int is typedef unsigned int I checked the ctfdump for /boot/kernel/kernel and found u_int is a resolved type. [14077] FUNC (rtalloc_fib) returns: 29 args: (1335, 5) Checking the CTF table "5" is found to be a resolved typedef. <4> INTEGER unsigned int encoding=0x0 offset=0 bits=32 <5> TYPEDEF u_int refers to 4 But since it shows unknown with dtrace -l -f o/p, one cannot directly use args[1]. Is this a known problem, any fix or workaround? -- Shrikanth R K ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"

Re: DTrace unable to dump typedef'ed argument
Nice. I checked that, things are looking more interesting now :) Thanks Ambrose.
